Question:

Which of the following is false regarding the Ellingham diagram?

Options:

It consists of plots of \(\Delta fG^0\) vs T

Ellingham diagrams are based on thermodynamic concepts

They do not tell us anything about the kinetics of the reduction process

They do not assume reactant-product equilibrium

Correct Answer:

They do not assume reactant-product equilibrium

Explanation:

The interpretation of ΔG° is based upon K \(i.e., \Delta G^0 = –RTlnK\). Thus, it is presumed that the reactants and the products are in equilibrium. But, this is not always true because the reactant/product may be solid.
